How do I sort?

One screenshot fills the screen. Put your thumb anywhere and swipe up, left or right; swipe down to set it aside for deleting. The window at the middle of the grid slides that way and shows the place it is on. Let go and the screenshot is filed there. Come back to where you started and nothing happens.

How do I reach the other places?

Swipe to a main and keep your thumb down: the places round it come to you. Let go on the one you want.

How do I name my places?

Open the menu and go to Folders. Rename any place, or put one of your own albums there.

How do I undo?

Undo is at the bottom left of the sorting screen. Undo takes back your last ten moves.

Where do my photos go?

Into albums in your own Photos app, in a folder called ZBAM. They are ordinary albums: open them, rename them or share them without ZBAM.

Where do deleted photos go?

Swipe down to set a photo aside for deleting. Nothing goes on the spot: photos to delete wait on their own screen until you confirm. Then they go to Recently Deleted in Photos, where iOS keeps them for 30 days.

How does the free week work?

The first seven days are free, with nothing to sign up for and no card. On day eight ZBAM asks you to choose how to keep it: once, or by the month. The App Store shows the price in your currency. Nobody is charged without pressing a button.

How do I restore a purchase?

Open the menu, then Settings, then Free week. On the screen with the two prices, press Restore purchase. ZBAM asks the App Store for what you have already bought with your Apple account.

How do I cancel?

A monthly plan is cancelled in Apple's own screen: open Settings on your iPhone, tap your name, then Subscriptions, then ZBAM. A one-time purchase has nothing to cancel.

What does ZBAM keep about me?

Nothing off your phone. No account, no server, no tracking. On the phone it keeps what it needs to work: your places, which photo went where so Undo can take it back, the week's counts, the day your free week began and, once you have bought ZBAM, that it is bought. The details are on the privacy page.
